Gardaí may have prevented another gangland killing in the capital.

They seized a loaded revolver in Dublin on Saturday afternoon and arrested two men.

It was part of ongoing investigations into organized crime and threats to life in the Dublin region.

The operation involved gardaí from the Garda National Drugs and Organised Crime Bureau (GNDOCB), Special Crime Task Force and Crime & Security.

It is being linked to the Hutch/Kinehan feud.

Gardaí arrested the two men - aged in their late 20s and early 30s - in the Dublin 3 area.

They were taken to garda stations in north Dublin, where they are being held under Section 30 of the Offences Against the State Act.

Gardaí also made a number of arrests after challenging a man in a car and another on a bicycle at Dublin's East Wall.

Investigations are continuing.
